HP Moonshot Switch Module CLI Command Reference
If you specify an IP address for the neighbor router, the following fields display:
Term Definition
Interface unit/slot/port
Neighbor IP
Address
The IP address of the neighbor router.
Interface Index The interface ID of the neighbor router.
Area ID The area ID of the OSPF area associated with the interface.
Options An integer value that indicates the optional OSPF capabilities supported by the neighbor.
The neighbor's optional OSPF capabilities are also listed in its Hello packets. This enables
received Hello Packets to be rejected (i.e., neighbor relationships will not even start to
form) if there is a mismatch in certain crucial OSPF capabilities.
Router Priority The OSPF priority for the specified interface. The priority of an interface is a priority integer
from 0 to 255. A value of '0' indicates that the router is not eligible to become the
designated router on this network.
Dead Timer Due The amount of time, in seconds, to wait before the router assumes the neighbor is
unreachable.
Up Time Neighbor uptime; how long since the adjacency last reached the Full state.
State The state of the neighboring routers.
Events The number of times this neighbor relationship has changed state, or an error has
occurred.
Retransmitted
LSAs
The number of LSAs retransmitted to this neighbor.
Retransmission
Queue Length
An integer representing the current length of the retransmission queue of the specified
neighbor router Id of the specified interface.
Restart Helper
Status
Indicates the status of this router as a helper during a graceful restart of the router
specified in the command line:
• Helping—This router is acting as a helpful neighbor to this neighbor. A helpful neighbor
does not report an adjacency change during graceful restart, but continues to advertise
the restarting router as a FULL adjacency. A helpful neighbor continues to forward data
packets to the restarting router, trusting that the restarting router's forwarding table is
maintained during the restart.
• Not Helping—This router is not a helpful neighbor at this time.
Restart Reason When this router is in helpful neighbor mode, this indicates the reason for the restart as
provided by the restarting router:
• Unknown (0)
• Software restart (1)
• Software reload/upgrade (2)
• Switch to redundant control processor (3)
• Unrecognized - a value not defined in RFC 3623
When the switch sends a grace LSA, it sets the Restart Reason to Software Restart on a
planned warm restart (when the
initiate failover command is invoked), and to Unknown
on an unplanned warm restart.
Remaining Grace
Time
The number of seconds remaining the in current graceful restart interval. This is displayed
only when this router is currently acting as a helpful neighbor for the router specified in the
command.
